I purchased this board in case my original crapped out. It looked pretty toasty last time I rebuilt my B'zzar head. Board quality looked great and the new board has many diagnostics features. It shows you if any opto's have failed, power to the board, and which opto's are currently triggered. Install took 2 minutes. Direct plug-n-play. The screw holes on the new board are marginally tighter than the original but it did not affect anything. I did not need to do any adjusting or fiddling, worked great as expected! Very happy there is a replacement now for people!

No errors during head test or during gameplay. As a note I did not have errors prior to installing the new board either.
